Medication is sometimes necessary, but the way it is used these days is very wrong. Medications such as antidepressants are often prescribed without any effort put into diagnosing. Very often there is something going on, sometimes medical, and sometimes situational. Prescribing antidepressants for that is kind of like prescribing aspirin for someone who's being punched in the face on a regular basis.

If you ask me - the big issue is that medication is used as a first resort rather than a last resort.

My mother was prescribed medication on her first visit to a psychiatrist; it not only did nothing for her OCD, but it also gave her suicidal ideation she did not previously have and scared her off from psychiatry for good. She's doing a lot better now, but it's mostly thanks to lifestyle changes that eliminated a lot of stressors from her life.

I had the same issue when I was severely depressed. The first therapist I talked to told me to see a psychiatrist for an antidepressant prescription and basically washed their hands of me, which only intensified my stress and anxiety. My current therapist still recommends medication, but she at least understands that I'm wary and we've made good progress through therapy itself.
